How To Fix Christmas Lights When Half The String Is Out?

Why are half of my LED Christmas lights out?

If one of your LED light strands isn’t working, it’s probably just because it has a bad bulb.

If one bulb dies, it can cause the rest of the strand to stop working.

The only way to fix the problem is to find the bad bulb.

Sometimes only a section of the lights will go out, making your job pretty easy.

Why does only half a string of lights work?

Don’t pull too hard on the wires. A loose bulb, broken socket or frayed wire is sometimes all it takes for the strand to malfunction. After taking down the lights, plug them in before storing them, to make sure they still work. The only tool you’ll need is a bulb tester in order to know how to fix Christmas lights.

Do LED Christmas lights burn out?

LED Christmas lights use light-emitting diodes, rather than filament to produce light. This new technology makes LED lights more efficient, durable, and longer-lasting than fluorescent incandescent lights. They don’t burn out, like other bulbs; and they also don’t get hot to the touch, so they’re a lot safer, too.

Do LED Christmas lights have fuses?

Like the incandescent strings before them, the LED strings have a fuse in series with each side of the AC line, located in the plug. Usually there is a trap-door in the plug to open and access the fuses, or there may be a section that pulls out.

Checking Faulty Christmas Tree Lights

  1. Plug the lights into an electrical outlet.
  2. Turn the light switch and the circuit breaker on.
  3. Check the fuse or fuses from the plug at the end of the light strand (usually the glass-cylinder type with a wire filament).
  4. If the fuse isn’t the problem, there’s a problem with a bulb.

How can you tell if a Christmas light fuse is blown?

Step 1 Blown Fuses

With the plug in hand, slide the door marked “Open” in the direction pointed by the arrow. Remove the two fuses, and inspect them by looking at them up against a bright background (such as the sky). If the fuse is good, you should see an unbroken strand of wire running between the two metal contacts.

Why are there 3 wires on Christmas lights?

Removing a bulb (or twisting it until the wires break) removes the shunt as well, so they all go out. These lights have three wires to carry electricity from end to end so that strings of lights can be daisy-chained together.
